Volume equals length times with times height
V= LwH
72=4 times 3 times H
72= 12H
Divide by 12
H= 6
Ok so the first thing you are going to do is chang the percentage into a decimal. 12 percent would change into 0.12, because in order to change a percentage into a decimal you move the decimal two places to the left. Next you would multiply 0.12 by 45 which gives you 5.4. But we are not done yet. By multiplying 0.12 x 45 we find how much weight she has gained. So our next and final step should be add 5.4 to 45 which gives us 50.4. Therefore your answer should be 50.4kg
Hope this helps!!!
Please tell me if I have made a mistake, I enjoy learning from mistakes!!
Have a great rest of your day!!
Answer:
6x^2 -38x +40
Step-by-step explanation:
Distribute the 2 to the first set of parentheses
(6x-8)(x-5)
then FOIL(mulitply in pairs first, outside, inside, last
6x*x
6x*-5
-8*x
-8*-5
6x^2 -30x -8x +40
Combine like terms
6x^2 -38x +40
Answer:
1: the answer cannot be determined because it doesn't state how big the area is. 2: 2.28125 gallons 3: 61%
Step-by-step explanation:
2. first find the area of the figure in square centimeters. the top trapezoid is (4+14)/2 * 10 = 90 and the bottom triangle is 14*8/2=56, so the total area is 146 sq cm. 1 sq cm corresponds to 2.5^2 = 6.25 square feet irl, so 6.25*146=912.5, and if you divide that by 400, you get 2.28125 gallons
3: Because there are 4 semicircles, 18/4=4.5, so the area of each semicircle is 4.5 pi. Therefore the area of a whole circle is 9 pi, so the radius of the circle is 3. That means the diameter of the circle, which is also the side of the square, is 6, so the area of the square is 36. Therefore the percent of the design that is green fabric is:
18pi/18pi+36
= 56.52/92.52
= about 0.611, which rounds to 61%.
84.1 because since 6 is greater than 5, you would round up to 1.
